We tested it on a few setups. The Vectors will not work on the Dura-Ace crank as it is too wide but it will work on stock SRAM Red, barely. Anything over 38mm wide will not work until they get a new version of the pod prepared.
We tested it with the Garmin 800 on a R3 with Rotor crank arms that worked and could not get the left pedal to show. The right pedal would work but it was showing nothing for left. The 810 that the store manager associated with the power meter showed both.
